I had a nightmare when I was young that I was in my house and I was being chased by some sort of sesame street monster. As I was running through all of the bedrooms, the beds turned into Thomas the train characters and started stretching up and choo-chooing really loud with stretched out faces, so I freaked out. Then the monster gobbled up my parents and ate them right in front of me and my siblings were gone. Then the monster grabbed me and was about to eat me :D
